<p>Actually, let me update the ticket to point to the code on that specific commit so it doesn't get out of date if you add in new changes</p>

<p><span class="user-mention" data-user-id="116114">@Paul Faria</span> maybe a better idea is if I create a different branch and we point them to that one or if you just fork it and point to that</p>

<p>whatever you prefer but I guess it would be easier to just give them a branch and this one is going to diverge for sure :)</p>

<p>wanted to point out that the issue says <code>Wait until you see an Empty</code>, that may not be true at the point in future someone runs this code because the query may return something :)</p>
